Title: Control of hydroelectric power station
Inventor: HACHITANI HIDEYUKI
IPC: H02P9/10
Filed: 1987-02-20
Abstract: PURPOSE:To keep the frequency of generator main circuit terminals constant even when the rotating speed of a generator is raised, by regulating the frequency of three-phase AC excitation at load interruption. CONSTITUTION:When a load is interrupted, the raise of the frequency of a three-phase AC exciting generator 2 is detected with a frequency detector 7. In accordance with this frequency raise, the frequency of AC excitation supplied to the field winding of the three-phase AC exciting generator 2 is regulated with a variable frequency exciting equipment 3 to control so that the frequency of main circuit terminals for the three-phase AC exciting generator 2 may be kept constant. In this way, since the frequency of main circuit terminals of the generator 2 is kept constant even at the load interruption, the power frequency of house circuit becomes constant which supplies the power from the generator main circuit through a transformer 5 for house power source.

Filed: 1988-02-18
Abstract: PURPOSE:To improve the clutter removing capacity of the title equipment by radiating transmitting waves having different frequencies at every pulse and removing clutters other than the clutter corresponding to the distance between each output distributed through a band-pass filter and a target. CONSTITUTION:A transmitter 3 is caused to radiate transmitting waves through a transmission-reception switch 2 by changing the frequency at every transmitting pulse. Then reflecting waves are led to band-pass filters 10-1-10-3 through a distributor 9 and each filter is always caused to output clutters corresponding to a target and the distance to the target only. The clutters outputted from the filters 10-1-10-3 are respectively converted into IF signals of the same frequency at frequency converters 4-1-4-3 and then their phases are adjusted to the same phase by means of phase regulators 11-1-11-3. The phase-adjusted signals are returned to the same line by an adder 12 and signals whose pulse repeating frequencies have become higher are obtained. Therefore, the transmitting pulse repeating frequency can be made higher and the clutter removing capacity can be improved.

Abstract: PURPOSE:To improve the reliability by providing a magnetic bridge type developer residual quantity detecting means and allowing this means to face a magnetic developer with the side wall of a developer tank between them and using the inside surface of the side wall as the detecting face. CONSTITUTION:When an electrostatic latent image formed on the surface of a photosensitive drum 1 reaches a developing area 2 in accordance with the rotation of the drum 1 in the direction of an arrow Z, the image is developed.

The detecting means is a magnetic bridge type detecting means and consists of a detecting head part 13 including primary and secondary coils electromagnetically connected to each other, an oscillating circuit to be the power source of the primary coil, and a phase detecting circuit. The phase detecting circuit detects the positional change from the differential output of the secondary coil to obtain an output signal corresponding to the change of the apparent permeability of the magnetic developer 24. The inside surface of a side wall 7a facing the front of the detecting head part 13 practically forms the detecting face, and differences of material and dimensions of the inside wall of the developer tank 7 are eliminated to prevent troubles in the vicinity of the detecting face of the detecting head 13.

Abstract: PURPOSE: To decrease the light emission saturation versus current, by providing each fluorescent substance stripe in the groove of triangle shape formed in the panel surface, in the stripe type color receiving tube.  
     CONSTITUTION: The grooves having equal triangle shape are formed in a given pitch at the cross section of short side direction of the stripes in the panel inside surface, and the red stripe 3, green stripe 4 and blue stripe 5 are sequentially arranged. In this case, taking the angle of stripe to taper as θ, the surface area of the fluorescent substance stripe is increased to 1/Cosθ times in comparison with the flat stripe. Thus, the current density is lowered in comparison with the flat even at the same current value. When the current value is increased, the saturation of light emission different by color is reduced to establish the color receiving tube without being changed with tone by the brightness.
